--------------------------------------------------------------
I'm trying to use an EJB 3.1 Timer to schedule a recurring task every 5 minutes.
I'm using JBOSS 6.0.0.Final.
This is the simple code I have deployed:
import javax.ejb.Schedule;
import javax.ejb.Stateless;
import javax.ejb.Timeout;
/**
* Session Bean implementation class AlerMonitorBean
*/
@Stateless
public class AlerMonitorBean {
/**
* Default constructor.
*/
public AlerMonitorBean() {
// TODO Auto-generated constructor stub
}
@Schedule(minute="0/5")
public void GestisciAlert() {
System.out.println("Gestisti Alert -
Tick"+System.currentTimeMillis());
}
@Timeout
public void GestisciTimeout(){
System.out.println("Timeout");
}
}
import javax.ejb.Schedule;
import javax.ejb.Stateless;
import javax.ejb.Timeout;
/**
* Session Bean implementation class AlerMonitorBean
*/
@Stateless
public class AlerMonitorBean {
/**
* Default constructor.
*/
public AlerMonitorBean() {
// TODO Auto-generated constructor stub
}
@Schedule(minute="*/5")
public void GestisciAlert() {
System.out.println("Gestisti Alert - Tick -> "+System.currentTimeMillis());
//TODO: insert code
}
}
I notice the following in Jboss Console:

15:40:59,003 INFO [STDOUT] Gestisti Alert - Tick -> 1294238459003
I expected that method "GestisciAlert" was called once every 5 minutes.....
Every 5 minutes Timer starts and activates target method several times (about once per
second) for a minute....
Then it stops and starts again after 4 minutes.
Hope someone can help me.
